The last release left this pinned to the git tag v1.5.1; release.sh expects
a committed path dep on the branch tip (it swaps path -> git tag only in the
tagged commit, matching bdemu). Restores that state so a local full-workspace
build links the sibling freemkv-unlock, and release.sh's path->tag swap works.
A CSS DVD whose main title was mis-detected as unencrypted (the up-front
crack scanned the largest cell first and starved its budget in that cell's
clear prefix) muxed scrambled sectors as plaintext at exit 0. CSS leaves
the pack/PES header clear, so an un-descrambled sector muxes as a
structurally-valid but corrupt PES packet with zero loss reported.
decrypt_keys_for_title resolves a DVD title's CSS key two ways:
- Fast path: reuse the scan's cracked key when its crack_span covers this
title's VTS (no re-read; on a live drive no second bus-auth).
- Crack: on a detection miss or a different VTS, crack from the title's OWN
extents in a SINGLE scan in natural PLAYBACK ORDER (never largest-first).
One scan = one CSS-locked early-bail, so a locked title is not re-hammered
per cell against a live drive (hard rule #2); the 50k-sector budget is the
same accepted bound the disc-wide scan uses. Cracked -> key; Unencrypted
-> clear; ScrambledUncracked -> hard-fail.
ensure_title_decryptable hard-fails an uncrackable DVD title even when
detection missed, and passes a title that resolved its OWN valid key
regardless of the disc-wide css_error. descramble_region is unchanged from
v1.5.1 (validated-key seed).
Also rename the unlocker report's DVD entry CSS -> DVD. Bump 1.5.2.
Add UnitKey.variant_number (0 = ordinary, 1..32 = forensic variant) with new/variant constructors, and aacs::variant_select — resolve a disc's single variant and classify each aligned unit (default / variant / drop foreign / conceal keyless). Correct IndividualSegment.tbl: the per-record field is the variant (cycles 1..32 on a retail disc), not a segment number — Segment.number -> Segment.variant.
Relicensed from AGPL-3.0 to MIT, effective 1.3.1 (<=1.3.0 remain AGPL). The CSS
content cipher and Stevenson title-key attack are attributed to their published
cryptanalysis (not libdvdcss); all libaacs/libbluray/libdvdread/libdvdnav name
references were dropped from comments while keeping the standard format/spec
descriptions. Also bumps to 1.3.1.
Parse ADV_OBJ/VPLST000.XPL (the real HD-DVD player playlist) with roxmltree
into one DiscTitle per <Title>: its PrimaryAudioVideoClip clips in order (EVO
via the .MAP sidecar), the titleDuration, the displayName, and the ChapterList.
A layer-break split (FEATURE_1+FEATURE_2, feature/feature_Divide) composes into
ONE title with the two parts as clips, each carrying its title-time in/out
points (45kHz ticks) for seamless-join splicing. Falls back to the clip-name
heuristic when no playlist is present.
Fixes unknown runtimes (real durations), poor names (FEATURE -> 'Main Movie'),
and gives authoritative composition + chapters. Validated on ANCHORMAN (97m),
SHAUN (99m), HARRY_POTTER (152m).
Bump to 1.3.0 and add the 1.3.0 changelog entry (FMTS/HD-DVD formats, AACS 2.1 variant chain, recovery seam, aacs module split, main-title-by-size, and the fixes since v1.2.2). Not tagged or pushed.
Adopt freemkv-unlock's split Unlocker trait: run_features drives the drive-prep capability, run_bus the content bus removal, each iterating unlockers until one doesn't decline (NotApplicable = try next; Ok or a real error stops).
unlocker_matrix now reports which drive-prep unlocker actually ran — LibreDrive removes the bus at the drive; Renesas unlocks features but leaves the bus to the cert. Wire product_id through to fu::DriveId.
Bump to 1.2.3.
libfreemkv now git-deps freemkv-unlock (which carries drive firmware and can
never be on crates.io), so libfreemkv itself can only be consumed by git tag.
The freemkv-unlock dep stays an interim path dep for local cross-repo dev; the
release script swaps it to a git tag in the tagged commit.
Add the freemkv-unlock dependency (path dep for local dev; re-pinned to a git
tag at release) and the consumption bridge: one generic ScsiAdapter mapping
libfreemkv's transport to the unlock contract, host-cert + DriveId mapping, and
run_unlockers() which news up all_unlockers() and runs the first matching one.
Additive — validates the dep resolves and the adapter compiles; the in-tree
registry/handshake/css path is still active and gets replaced in 4b.
keydb I/O moves out of libfreemkv into freemkv-keysources
(KeydbSource::save / ::update). Delete src/keydb.rs entirely (save,
http_get, default_path, write_atomic, UpdateResult) and drop `pub mod
keydb;` — http_get had no real callers. The shared Keydb* Error variants
stay in error.rs (keysources raises them; the every-error-has-a-code
contract depends on them). flate2 is no longer used here, so drop it
from Cargo.toml (zip stays for labels/jar.rs).
CHANGELOG: note the keydb-I/O move; reword the rc.5.2
DefaultDecodedFieldDuration entry to state only the action taken (the
revert) rather than an unverified Windows-fps outcome.
